Both vertical machining centers and horizontal machining centers belong to machining centers. The main difference between them is that the Z-axis structure is different. The Z-axis of the vertical machining center moves vertically downwards to complete the processing, while the Z-axis of the horizontal machining center moves horizontally downwards to complete the processing.When choosing a machining center, factors such as processing requirements, equipment performance, maintenance costs, and supplier services and support need to be considered.
The following are some suggestions on how to choose a vertical machining center or a horizontal machining center according to specific needs:
Characteristics of processed parts
Shape and size of the part:
1: Vertical machining centres are usually the better choice if the part is predominantly flat, plate-like, or is relatively short in height and has a large number of features in one plane. Examples include printed circuit boards, thin sheet metal, etc.
2: Horizontal machining centres are more advantageous for parts that have multiple sides to be machined, especially long and thick box-like parts. For example, automotive engine block.
Location and number of machined faces:
1: When the faces to be machined are mainly concentrated on the top and sides, vertical machining centres can better meet the demand.
2: If the parts need to be machined in multiple sides with high accuracy and efficiency, and multiple faces need to be machined in one clamping, horizontal machining centre is more suitable.
Equipment performance:
1: Vertical machining center: simple structure, small footprint and low price.The workbench is a T-slot workbench with a cross-slide structure. There are two sets of motion mechanisms responsible for the movement of the workbench perpendicular to each other. The workbench with X-direction feed is covered by the guide rail responsible for Y-direction feed.Its columns generally do not move, and are generally made as thick as possible in order to pursue rigidity.There are also moving column vertical machining centers, which have greater power requirements for the driving motor of the column.
2: Horizontal machining center: it is easy to remove chips during processing, and the processing condition is relatively ideal, but the structure is complex and the price is higher.The workbench only moves in the X or Y direction. The form of the workbench is generally a rotating workbench with a dot matrix screw hole workbench, which is relatively easy to choose an exchange type double workbench.The column must be a moving column type. The positive T-shaped horizontal machining center column moves in the X direction, and the inverted T-shaped horizontal machining center column moves in the Z direction.The structure of the mobile column requires that the column must be as light as possible under the premise of meeting the rigidity. Foreign machine tools often use steel plate welding structure to solve this problem.
In summary, vertical machining centers are suitable for processing small and simple parts, while horizontal machining centers are suitable for processing large and complex parts.When choosing a machining center, it should be considered comprehensively according to the specific processing needs and budget.
